# hostaddr(1)

## NAME

         hostaddr - show ethernet address, IP address or hostname

## SYNOPSIS

         hostaddr [-eia] [-E eth-device] [-I ip-device]

## DESCRIPTION

         Without any of the -eia options, hostaddr shows the ethernet address,  IP
         address  and  hostname  of the local host on one line in the given order.
         With options only the wanted fields are shown, still in the  same  order,
         not in option order.

## OPTIONS

         -e   Show the ethernet address.

         -i   Show the IP address.  This will not work if no IP address  has  been
              found by RARP or by setting it with ifconfig(8).

         -a   Show the fully qualified hostname.  The IP address is shown again if
              it can't be translated to a host name.  (This usually indicates that
              the DNS reverse address translation tables are incomplete.)

## SEE ALSO

         ifconfig(8), rarpd(8), nonamed(8), set_net_default(8), boot(8).

## DIAGNOSTICS

         "Timeout"
         Hostaddr timed out trying to get the IP address.   This  means  that  the
         network  connection  is  out of order or that the setup of the machine is
         bad.
